You could add some more highs in the snare to begin with. Also make it slightly shorter, so it has a bit more punch.
Here and there a variation in the drums wouldn't hurt either.

I love the parts without drums the most so far, although I must say your drops have good potential!
At the end though the drop gets really boring. I think the best thing to do is make a switchup after 8 bars of half-time drums.
Just make some kind of break and maybe a build up synth that works up to the drum and bass rhythm again. This will get the dynamic back in the song, so that it keeps being interesting to listen to.

At your soundcloud I gave some more tips or made clear what I thought was really cool and what could use something extra.

Like it man.. I prefer the first drop to the second, as not a huge fan of the prolonged half time 'vibe', but that's just my personal taste.. Hope you can sort out the refix without much trouble after the loss of files..

I GOT IT BACK! fuck school work that can come second. Slaved away at it until I got it back to where I was. Thank god for resamples, I saved the basslines and some of the sidechained synths. Keeping a log now too, so I can remember what drums pieces I used and the volume levels....
